Having seen Boston at work and at play, we now ask ourselves where the food comes from to feed this vast multitude. Its meats, flour, and grain of all kinds are brought into its huge freight stations from the West. Its great ocean trade with the ports in the South as well as in Europe and Asia supplies other food necessities and luxuries. New England is a great dairy center, and much of the city's milk, butter, and other dairy products comes to Boston each morning from New Hampshire, Vermont, and western Massachusetts. The purity of the milk is carefully watched, and it is impossible to buy even a pint of milk in anything but a sealed jar. Boston's drinking-water is equally well guarded. The water, as well as the sewage, is under the control of the Metropolitan Water and Sewage Commission. There is a high-pressure distributing station at Chestnut Hill, which gives power sufficient to force water to the highest of Boston's buildings. The sewage of the down-town sections of the city is collected in a main drainage system, pumped through a tunnel under Dorchester Bay to Moon Island, held in large reservoirs, and discharged into the water when the tide is going out. The sewage of the outlying districts is conveyed to various places in the harbor and discharged into the water at a depth of thirty or forty feet, where it can be quickly carried out to sea. Our stay in Boston is now at an end. Not only have we traveled over many miles of her streets and visited her famous State House, her busy wharves, and her interesting playgrounds, but we have reviewed many events of her thrilling history. What of all we have seen or heard is it most important for us to remember? First, that Boston is the fifth city in size in the United States; second, that she is the capital city of Massachusetts; third, that she is the chief trade center of New England; and fourth, that among America's cities she ranks second only to New York in foreign commerce. Then we must not forget the important place she holds in the early history of our country. As we traveled into Boston, so we will journey out again. And with the last of the great city fading from our view, we call to mind the large-hearted Blackstone and say to ourselves, "Quite a change from the hermit's home on the sunny slope of Beacon Hill." =BOSTON= FACTS TO REMEMBER Population (1910), nearly 700,000 (670,585).
